The plurality of disks 211a and 212a are fixed to each of the two shafts 211 and 212 so as to rotate integrally with the two shafts 211 and 212. Here, the radius of the plurality of disks (211a, 212a) should be more than a certain size so that a part of the edge overlaps between the two axes (211,212).

In the glass tube material 20a introduced into the first rotating means 210 by the feeding and feeding device 100 according to the above configuration, the neighboring disks having a part of the edges overlapped between neighboring axes 211 and 212. Along the upper portion between the (211a, 212a) in the axial direction. That is, the glass tube material 20a is supported by the neighboring disks 211a and 212a while its outer peripheral surface is in contact with the outer peripheral surfaces of the neighboring disks 211a and 212a at the same time. The glass tube material 20a supported as described above is rotated by rotating the two shafts 211 and 212 at the same speed in the same direction.

On the other hand, the first rotating means 210 is preferably longer than the length of the glass tube material 20 is introduced into the first rotating means 210 by the feeding and feeding device 100. That is, one side of the first rotating means 210 in the axial direction of the alignment column 110 described below is installed and the other in the axial direction of the first rotating means 210 is injected into the glass tube material Since the first heating means 220 and the cutting knife 230 and the like for cutting one end of the 20a to a predetermined length are installed, the two shafts 211 and 212 of the first rotating means 210 have at least the length thereof. The length of the alignment stage having a length corresponding to the length of the glass tube material 20 and the length to ensure a space in which the first heating means 220 and the cutting knife 230, etc. can be installed It is preferred to be larger than the sum.

In particular, the first rotating means 210 of the glass tube material 20a cut into two parts by the cutting device 210, the glass tube 21 of a predetermined length supplied to the next flare forming apparatus 300 is the first It is provided with a configuration for taking out from the rotating means (210). That is, among the plurality of disks 211a and 212a of the first rotating means 210, the plurality of disks contacting and supporting the glass tube 21 having a predetermined length supplied to the flare forming apparatus 300 may be formed on each outer circumference. Grooves 211b and 212b are formed at positions corresponding to the same phase with respect to the vertical line, and serve as a transfer device for transferring the glass tube 21 of the predetermined length between neighboring disks of the transfer device described below every rotation. The configuration as described above is roughly the same as the configuration of the transfer apparatus described below, which will be described in detail with reference to the transfer apparatus.

The first heating means 220 is for heating a predetermined point of the glass tube material 20a rotated by the first rotating means 210, referring to the torch 221 of the first heating means. And Tochi reciprocating drive arm 222. The torch 221 moves the flame downward at a point corresponding to the length of the glass tube 21 of the predetermined length from one end of the glass tube material 20a rotated by the first rotating means 210. Radiating to heat the glass tube material (20a), and is connected to a predetermined combustion gas supply source not shown in the figure. In particular, the torch 221 is fixed to one end of the torch reciprocating rotational arm 222 is moved up and down by the reciprocating rotational movement of the torch reciprocating rotational arm 222.

The torch reciprocating pivotal arm 222 is connected to the hinge shaft 223 having a central axis parallel to the axial direction of the glass tube material 20a on which the opposite end on which the torch 221 is installed is connected to the first rotating means 210. It is rotatably installed at the top of the Accordingly, the torch reciprocating arm 222 is reciprocated up and down by the hinge shaft 223 is connected to a predetermined torch reciprocating arm driving unit not shown in the figure, thereby reciprocating rotation. The reason for the reciprocating movement of the torch 221 up and down as described above is that the glass tube 21 having a predetermined length, which is a part of the glass tube material 20a cut into two parts by the cutting device 200, is the cutting device ( The torch (while being taken out of the 200 and supplied to the flare forming apparatus 300 and the remaining portion of the glass tube material 20a cut in two minutes is fed to the cutting apparatus 200 for cutting. 221 is moved upward to prevent the glass tube material 20a from being heated.

The cutting knife 230 periodically contacts the outer circumferential surface of the glass tube material 20a at a predetermined point of the glass tube material 20a heated by the first heating means 220 to make the glass tube material 20a two. It is for cutting. The cutting knife 230 is fixed to one axis of the first rotating means 210 (an embodiment fixed to the shaft 212 is shown in the drawing) is the glass tube is heated by the first heating means 220 Rotate integrally with the shaft 211 or 212 at a lower portion of the material 20a. In particular, the cutting knife 230 has a blade 231 formed on a circumference having a constant radius from the center of the shaft (211 or 212). Since the predetermined radius is substantially the same as the radius of the plurality of disks (211a, 212a) of the first rotating means 210, the blade portion 231 is rotated by the cutting knife 230 the first heating means ( Periodic contact with the outer circumference of the glass tube material 20a heated by 120, and also periodically contacts the water contained in the cutting can 240 located below the cutting knife 230. On the other hand, in order for the glass tube material 20a to be cut by the contact of the blade part 231, the blade part 231 should contact the outer circumferential surface of the glass tube material 20a, so that the outer circumferential surface thereof should be circumscribed. The length is preferably at least longer than the outer circumferential length of the glass tube material 20a.

The cutting bucket 240 is for accommodating the cutting water 240a that wets the blade 231 and is installed below the cutting knife 230 so as not to interfere with the rotating cutting knife 230. The principle that the glass tube material 20a is cut by contacting the blade 231 while being heated by the first heating means 220 is because cracks are generated in the glass tube material 120a due to a sudden temperature difference. That is, when the cold blade portion 231 of the cutting knife 230 is in contact with the local point on the outer circumferential surface of the glass tube material 20a heated by the first heating means 220, there is a considerable temperature difference between the local point and its surroundings. As a result, a crack occurs at the local point of the glass tube material 20a. However, since the blade portion 231 of the cutting knife 230 is in contact with the hot glass tube material 20a periodically to increase the temperature, it is necessary to cool it. Therefore, the blade 231 is cooled by periodically contacting the blade 231 with the cutting water 240a. In particular, the moisture of the cutting water 240a soaked in the blade portion 231 is supplied to the outer circumference of the glass tube material 20a. When the water is supplied to the outer circumference of the glass tube material 20a as described above, the temperature difference is further increased. It becomes bigger.

On the other hand, the cutting device 200 further comprises a first pressing means (250).

The first pressing means 250 is a glass tube material 20a is rotated by the first rotating means 210 while being heated by the first heating means 220 is cut by the cutting knife 230 A downward force is applied to the upper portion of the glass tube material 20a so as to stably adhere to the disk of the first rotating means 210. In particular, in order to accurately cut the glass tube material pipe 20a, it is preferable that a line drawn while the blade portion 231 is in contact with the outer circumferential surface thereof becomes a closed curve. Accordingly, while the glass tube material 20a is being cut, the glass tube material 20a needs to be rotated while being supported in the correct posture by the neighboring disks 211a and 212a of the first rotating means 210. It is made by pressing the glass tube material 20a downward against the disk of the first rotating means 210. In particular, the position of the first pressing means 250 presses the glass tube material 20a because the posture of the shorter length of the portion cut into two parts by the cutting device 200 is likely to become unstable. It is preferable to be the outer circumferential surface of a part which becomes the glass tube 21 of a predetermined length supplied to the flare forming apparatus 300 on the basis of the point where 20a is cut into two parts.

Referring to the drawings, the first pressurizing means 250 for the above operation includes a first pressing roller 251 and a first pressing roller reciprocating pivoting arm 252. The first pressing roller 251 is to contact the upper portion of the outer peripheral surface of the glass tube material 20a rotated by the first rotating means 210 to press the glass tube material 20a downward. The first pressing roller 251 is rotatably mounted on one end of the first pressing roller reciprocating pivot arm 252 to reciprocate up and down by rotating the first pressing roller reciprocating pivot arm 252. As described above, the glass tube material 20a is pressed downward while the glass tube material 20a is cut while being rotated by the first rotating means 210 by reciprocating the first pressing roller 251 up and down. Among the portions in which the glass tube material 20a is cut into two parts, a portion corresponding to the glass tube 21 having a predetermined length is taken out from the cutting device 200 and supplied to the flare forming apparatus 300 and into the two parts. While the other portion of the cut glass tube material 20a is fed to the cutting device 200, the first pressure roller 251 is taken out of the glass tube 21 of the predetermined length and the glass tube material 20a to be fed. It is moved upwards so as not to interfere.

The first pressurized roller reciprocating arm 252 has the opposite end where the first pressurized roller 251 is installed is connected to a predetermined rotation shaft, and the pivot shaft is driven by the first pressurized roller reciprocating arm driver not shown in the drawing. Rotate around. In the drawing, the pivot shaft is not provided separately, and the first pressurized roller reciprocating arm 252 is rotatably installed on the hinge shaft 223 to which the torch reciprocating pivot arm 222 is fixed. A rotating example relative to 223 is shown.

Hereinafter, the glass tube material 20 is introduced into the first rotating means 210, and the glass tube material 20a is fed in the axial direction from the upper portion of the first rotating means 210 to the cutting device 200. The feeding and feeding device 100 for supplying by a predetermined length will be described.

The guide part 121 supports the stopping rods 122 and 123 so that the two stopping rods 122 and 123 can reciprocate up and down. The guide portion 121 is a lower portion of the shaft (shaft 212 in the case of the drawing) is located close to the alignment zone 110 of the two shafts (211,212) of the first rotating means (210). It is positioned at and fixed to a predetermined base not shown in the drawings. The guide portion 121 has two guide holes vertically penetrating into which the two stopping rods 122 and 123 are to be inserted, respectively. It is formed parallel to each other in a symmetric position with respect to).

The two stopping rods 122 and 123 are inserted into the guide holes so as to reciprocate up and down. Each of the protrusions of the stopping rods 122 and 123 protruding upward from the guide part 121 may be disposed between one shaft 212 of the first rotating means 210 positioned above the guide part 121. It extends higher than the axis of one rotating means 210. That is, one shaft 212 of the first rotating means 210 passing through the upper portion of the guide portion is positioned between the upper ends of the stopping rods 122 and 123. The stopping rod protrusions 122a and 123a are protruded toward each other so as to face each other at an upper portion of the shaft positioned above the guide portion 121 so as to face each other. Is formed. In particular, the stopper rod protrusions (122a, 123a) is extended to a position that can take the glass tube material 20 located on the lowest slope of the alignment zone 110 in the upward direction, the upper end of the glass tube material ( 20) is sharply formed so that extraction can be easily performed. Meanwhile, one side of each of the guide holes is opened to expose a central portion of the stopping rods 122 and 123 to one side. The exposed center portions of the stopping rods 122 and 123 are connected to each other by the link rods 124 so that the two stopping rods 122 and 123 are simultaneously moved in opposite directions. That is, both ends of the link rod 124 are rotatably connected to the respective center portions of the stopper rods 122 and 123, and the center portion thereof is a link rod rotating shaft installed between the guide holes at one side of the guide portion 121 ( 124a) is rotatably installed. Accordingly, when the two stopping rods 122 and 123 move in one upward direction (or downward direction), one end of the two stopping rods 122 and 123 is hinged to the stopping rod 122 or 123. The link rod 124 is rotated about the link rod pivot shaft 124a, and the other stopping rod 123 or 122 connected to the other end of the link rod 124 is downward (or upward). Will be moved to. That is, the two stopping rods 122 and 123 are always moved in opposite directions by the link rod 124 at the same time. The stopping rod reciprocating driving unit 125 is for vertically reciprocating the stopping rods 122 and 123 and is connected to a lower end of any one of the stopping rods 122 and 123. The stopper rod reciprocating drive part 125 because the feeding means 120 supplies the glass tube material 20 one by one to the first rotating means 210 by fast reciprocating driving of the two stopping rods 122 and 123. The pneumatic cylinder with fast operation is suitable. The stopping rod reciprocating drive unit 125 is operated by receiving a signal transmitted from the sensor 160.

Accordingly, the glass tube material 20 arranged on the alignment stand 110 is not caught by the stopper rod 122 and is not introduced into the first rotating means 210. On the other hand, when the glass tube material 20a supplied to the first rotating means 210 and fed toward the cutting tooth 200 completely exits the alignment zone 110, the sensor 160 detects this and stops the stopper. It delivers to the rod reciprocating drive unit (125). The stopping rod reciprocating drive unit 125 receiving the signal moves the stopping rod 123 downward, and at the same time, the other stopping rod 122 is moved upward. Accordingly, the plurality of glass tube materials 20 stopped by the stopper rod 123 are moved downward along the inclined surface of the alignment zone 110, and one of the glass tube materials positioned at the bottom thereof is the stopping. The rod 123 is rolled between two disks 211a and 212a adjacent to the first rotating means 210 and supplied to the first rotating means 210. However, the other glass tube material following the one glass tube material located at the bottom is caught by the stopper rod 122 moved upward. On the other hand, immediately after one of the plurality of glass tube material 20 is supplied to the rotating means 210, the stopper rod reciprocating drive unit 125 is returned to its original state. That is, the stopping rod 123 is moved upward and the other stopping rod 122 is moved downward. Accordingly, the plurality of glass tube materials 20 stopped by the stopper rod 122 are stopped while caught by the stopper rod 123 moved upward.

The feeder 140 is for feeding the cutting device 200 by a predetermined length in the axial direction the glass tube material 20a supplied to the upper portion of the disk (211a, 212a) adjacent to the first rotating means (210) It includes a feeding part, a pressing part, and a stopper part.

That is, the feeding part roller 141 rotates so that the direction of the linear velocity of the upper circumferential surface thereof is parallel to the axial direction of the glass tube material 20a and toward the stopper, and the contact portion with the glass tube material 20a The axial force is applied to the glass tube material 20a by the friction generated above. The feeding part roller 141 is rotatably installed in the feeding part base 142 installed under the shafts 211 and 212 of the first rotating means 210. On the other hand, the glass tube material 20a supplied to the upper portion of the first rotating means 210 is fed to the cutting device 200 by a predetermined length while being rotated by the first rotating means 210 while being fed If it is in contact with the roller 141, the rotation by the first rotating means 210 is not made smoothly because of friction for feeding. Therefore, the feeding part roller 141 is in contact with the glass tube material 20a only while the glass tube material 20a is fed, and the upper and lower parts of the glass tube material 20a are separated from the glass tube material 20a. Should be moved to, the vertical reciprocating motion of the glass tube material (20a) is made by the base reciprocating drive described below. The roller rotation driving unit is for rotating the feeding unit roller 141, and includes a motor 143c. The motor 143c is fixed to the feeding unit base 142 and generates a rotational force capable of rotating the feeding unit roller 141. The rotational force generated by the motor 143c is transmitted to the feeding part roller 141 through the chain 143a and the belt 143b connecting the predetermined shaft and the shaft installed in the feeding part base 142. The feeding unit base 142 is installed above the base 148 to be moved up and down by the base reciprocating driving unit described below. That is, the feeding unit base 142 supports the feeding unit roller 141 and the motor 143c and the like, which are reciprocated vertically together with them. The base reciprocating drive unit is for reciprocating the feeding unit base 142 up and down, and includes a cylinder 144, a guide rod 145, and a guide 146. The guide 146 has a through hole in which the guide rod 145 is inserted and installed at the center thereof, and an upper end thereof is a base 148 at which the feeding part base 142 is installed at a lower side of the feeding part base 142. It is fixed to the bottom of the. The base 148 on which the guide 146 is installed is formed with a hole communicating with the through hole of the guide 146. The guide rod 145 is inserted into the through hole of the guide 146 so that the upper end protrudes to the upper portion of the base, and can be moved up and down. An upper end of the guide rod 145 exposed to the upper portion of the base 148 is connected to and fixed to a bottom surface of the feeding unit base 142. Accordingly, when the guide rod 145 moves up and down, the feeding unit base 142 and the motor 143c and the feeding unit roller 141 installed on the feeding unit base 142 are moved up and down. On the other hand, the cylinder 144 is connected to the lower end of the guide rod 145 to move the guide rod 145 up and down is installed in a predetermined fixing member. Referring to the drawings, the cylinder 144 is fixed to the cylinder fixing bracket 146a extending to one side from the lower end of the guide 146, the lower end of the cylinder shaft of the cylinder 144 the guide rod 145 Is connected to the lower end of the cylinder shaft fixing bracket (144a).

The pressing part is for pressing the glass tube material 20a downward so that the glass tube material 20a moved in the axial direction by the feeding part is in close contact with the feeding roller 141, and the feeder pressing roller 151 and this And a configuration for reciprocating.

The feeder pressing roller 151 is installed on the first rotating means 210 to be rotated in contact with the upper portion of the glass tube material 20a to be fed in contact with the feeding roller 141. Referring to the drawings, the base 148 is provided with a feeder pressing roller rotating arm support 153 so as to protrude upward from the rotating means 210 at one side of the first rotating means 210, feeder pressing roller rotation The copper arm 152 is hinged to an upper end of the feeder press roller rotation arm support 153 so that one point between both ends thereof is rotatable about a rotation axis in a direction parallel to the center axis of the glass tube material 20a. The feeder pressing roller 151 is rotatably installed at one end of the feeder pressing roller pivot arm 152 extending toward the feeding roller 141. In addition, the other end of the feeder pressing roller rotating arm 152, the feeder pressing roller 152 is installed, the cylinder shaft of the cylinder 154 for driving the feeder pressing roller rotating arm 152 is connected, the cylinder 154 is fixed to the extension bracket 153a extending toward the cylinder 154 from the upper end of the feeder presser roller arm support 153. Accordingly, when the cylinder 154 is operated, the feeder pressurized roller pivot arm 152 is reciprocated, and the feeder pressurized roller 151 reciprocates up and down. The reason why the feeder pressing roller 151 is reciprocated up and down as described above is because the new glass tube material 20 and the feeder pressing roller 151 are introduced into the first rotating means 210 from the alignment zone 110. Not only does not interfere with, the feeder pressure roller 151 to be separated from the glass tube material 20a so that the glass tube material 20a is smoothly rotated by the first rotating means 210 while not being fed. It is for.

On the other hand, the glass tube material 20a by the feeder 140 should be fed to the cutting device 200 by a predetermined length. Therefore, the feeder 140 further includes a stopper part installed in front of the direction in which the glass tube material 20a is fed. The stopper part includes a stopper 156 that limits the length of the glass tube material 20a to be fed by hitting the distal end of the glass tube material 20a moved by the feeder 140 at one end. In particular, the stopper 156 is advanced back and forth in the axial direction of the glass tube material 20a by the stopper reciprocating drive unit 156a. The reason why the stopper 156 is moved forward and backward as described above is that the portion corresponding to the glass tube 21 having a predetermined length among the two parts of the glass tube material 20a cut by the cutting device 200 is the flare forming apparatus ( It is for reversing the stopper 156 so that the end thereof is not caught by one end of the stopper 156 while being supplied to 300. That is, the stopper 156 is advanced while the glass tube material 20a is fed by the feeder 140, and the cut glass tube 21 having a predetermined length is taken out from the cutting device 200 to form the flare forming apparatus. It is reversed while being supplied to 300.

The feeder 140 is installed on the opposite side where the stopper 156 is located on the basis of the point where the cutting knife 230 of the cutting device 200 is installed. In particular, one is installed in close proximity to the cutting device 200 is to feed the glass tube material 20a, which becomes shorter and shorter, into the cutting device 200 until the end.

By the above configuration, the feeder 140 is operated as follows.

While the glass tube material 20a is cut by the cutting device 200 while being rotated by the first rotating means 210, the feeding roller 141 is moved downward and the feeder pressing roller 151 is Both are moved upwards to maintain a state away from the glass tube material 20a.

The housing 611 has the clamping means 620, a power transmission means, and a clutch. 615 is installed. Bearings 611a and 611b are inserted into upper and lower ends of the through hole of the housing 611, and guide parts 621 described below of the clamping means 620 are inserted into the inner ring. On the other hand, one side of the side wall of the housing 611 between the two bearings (611a, 611b) is formed with a gear binding window 612 partially cut through from the outside to the inside. The gear binding window 612 is formed such that the chuck gear 614 installed inside the housing 611 is exposed to the outside to be engaged with the driving gear 604. On the other hand, the chuck 610 is very hot by the heat of heating the bulb material pipe. Therefore, since the bearings 611a and 611b may be deteriorated, it is necessary to cool the chuck 610 in order to prevent this, and a cooling water flow path 613 through which cooling water passes is formed in the housing 611. One end of the cooling water flow passage 613 is connected to one end of the water supply pipe 613a shown in FIG. 17, and the other end thereof is connected to one end of a predetermined drain pipe not shown in the drawing. Accordingly, the coolant flows into the cooling water flow path 613 through the water supply pipe 613a from the cooling water storage container 616 fixed to the upper portion of the rotary table 602 and integrally rotated with the rotary table 602. And discharged to the outside through the drain pipe.

The clamping means 620 is installed in the housing 611 to be rotatable about a predetermined axis. The clamping means 620 has a predetermined through hole 621a formed along the axis line, and has a predetermined length such that the central axis of the bulb material pipe 40 substantially coincides with the axis below the through hole 621a. It is for clamping the gripping portion 40b, which is the upper end of the bulb material pipe 40, and includes a guide portion 621, a gripping portion, and a gripping portion driving means. The clamping means 620 is supplied to the bulb material tube 40 when the clamping release device (720,730) described below when applying an external force of a predetermined size or more to the clamping means 620 or clamped the upper end of the bulb material tube (40) It is characterized in that the holding portion is opened to release.

The guide part 621 is for the holding part and the holding part driving means is installed, the embodiment shown in the drawing is the through hole in a constant axial direction which is the central axis of rotation of the clamping means 620 in the center ( The outer periphery of 621a is extended by a predetermined length, and the gripping portion is installed at the lower end thereof, and the gripping portion driving means is installed above the gripping portion to drive the gripping portion. The upper portion of the guide portion 621 is inserted into the inner ring of the bearing (611a, 611b), accordingly, the clamping means 620 is rotatably installed in the housing (611).

The gripping portion is to clamp the upper end of the bulb material tube 40 of a predetermined length so that the central axis and the axis of the bulb material tube 40 substantially coincide under the through hole 621 a of the guide portion 621. A portion of the gripping portion clamping the bulb material tube 40 is installed at a lower end of the guide portion 621 to be positioned below the through hole 621a of the guide portion 621. The gripping portion includes a jaw base 622 installed at the lower end of the guide portion 622, and a jaw 623 rotatably disposed to the outer edge of the jaw base 622 to be radially symmetrical. That is, the jaw 623 is disposed on the jaw base 622 so as to be rotatable in a plane including the axis and arranged at regular intervals on the same circumference. Accordingly, when the jaw 623 is rotated in a direction in which the lower end thereof retracts about the axis, the lower end contacts the outer circumference of the upper end of the bulb material pipe 40 to clamp the bulb material pipe 40. When the lower end is rotated in the direction away from the axis, the lower end is separated from the outer circumferential surface of the clamped bulb material tube 40, thereby placing the bulb material pipe 40. The jaw 623 is in contact with the lower surface of the pressing plate 624, the top of which is described below, the upper end is extended to the top of the jaw base 622 for this purpose. In addition, the upper end of the jaw 623 is in contact with the lower surface of the pressing plate 624, the upper end of the jaw 623 and the pressing plate 624 moves relative to each other at the contact surface, so that the jaw ( At the top of the 623, a jaw roller 623a is installed.

The gripping part driving means is installed in the guide part 621 to rotate the jaw 623 in the direction in which the lower end of the jaw 623 is retracted or separated from the axis, the embodiment shown in the figure The upper and lower parts of the guide 621 is fixed to the jaw base 622 spaced apart from the jaw base 622 and the guide 621 between the fastener 625 and the jaw base 625 up and down The pressing plate 624 installed on the guide part 621 and the upper end are supported by the fixture 625 and the lower end is supported on the upper surface of the pressing plate 624 by a spring ( 626). The pressing plate 624 is moved downward by the spring 626 elastic force, and is moved upward by an external force of a predetermined size or more applied by the clamping release devices 720 and 730 described below.

By the above configuration, the clamping means 620 is operated as follows.

The jaw 623 pivots below the jaw base 622 when the pressing plate 624 applies a force to the jaw roller 623a while moving downward in the elastic force of the spring 626. The jaw 623 is rotated in the direction in which the lower end of the upper and lower sides thereof are centered about the axis. Accordingly, the lower end of the jaw 623 clamps the supplied bulb material tube 40, and the clamping is continuously maintained by the elastic force of the spring 626. On the other hand, when the clamping release means 720 and 730 described below on the lower surface of the pressing plate 624 apply an external force of a predetermined size or more to push the pressing plate 624 upward, the jaw roller 623a is the lower surface of the pressing plate 624. At the same time, the jaw 623 is rotated in a direction in which the lower end thereof is separated from the axis by its own weight. Accordingly, the gripping portion may be supplied with a new bulb material tube 40 or release the clamping of the processed bulb 62. In order to smoothly operate the clamping means 620 as described above, the clamping means 620 has the following characteristics. First, in order for the jaw 623 to smoothly rotate under the force of the press plate 622, an extension line in the direction of the force applied by the press plate 624 to the jaw roller 623a is defined by the jaw 623. Pass through the outside of the circumference installed in the jaw base (622). In addition, in order for the jaw 623 to be rotated by its own weight, an extension line in the gravity direction applied to the center of gravity of the jaw 623 must pass through the inside of the circumference. On the other hand, as described below, when the gripping portion receives a new bulb material tube 40 or releases the clamping of the processed bulb 62, rotation of the gripping portion needs to be stopped. The clamping means 620 is characterized by being stopped by an external force applied to the pressing plate 624 by the clamping release means (720,730).

The chucking force transmitting means is installed in the housing 611 and receives the power for rotating the clamping means 620 from the gripping portion driving means and transmits the clamping means 620 to the clamping means 620. An embodiment includes a chuck gear 614. The chuck gear 614 is inserted into the guide part 621 so as to be relatively rotatable with the guide part 621, and is located inside the housing 611. At this time, the gear tooth of the chuck gear 614 is exposed to the gear binding window 612 a portion of the gear teeth to be engaged with a predetermined drive gear 604 through the gear binding window 612. The chuck gear 614 meshed with the driving gear 604 as described above receives the rotational force from the driving gear 604 and transmits the rotational force to the guide part 621 through the clutch 615.

The clutch 615 is for controlling the rotational force transmitted from the chucking force transmitting means to the guide part 621, and an external force of a predetermined size or more is applied to the clamping means 620 by the clamping release devices 720 and 730. The rotational force transmitted to the guide part 621 is blocked. The clutch 615 may be embodied in various configurations, but the embodiment illustrated in the drawing is installed in a radially penetrating hole facing the guide part 621 from the outer circumferential surface of the chuck gear 614. The friction clutch in which the adjusting screw 615a, the friction pad pressing spring 615b, and the friction pad 615c are sequentially installed in the radial direction from the outside to the inward direction is used. The friction pad 615c receives the elastic force of the friction pad pressing spring 615b and adheres to the outer circumferential surface of the guide part 621 by the configuration as described above, so that the friction pad 615c and the guide part 621 are provided. Friction is generated at the contact portion of the, so that when the chuck gear 614 rotates, the guide portion 621 also rotates. On the other hand, if a torque greater than the magnitude of the torque generated by the friction force is applied between the guide portion 621 and the chuck gear 614, the contact surface between the friction pad 615c and the guide portion 621 is slipped. Is generated. That is, even when the chuck gear 614 is rotated by receiving the rotational force from the drive gear 604, the clutch 615 is slipped when a predetermined torque or more is applied to the clamping means 620. And relative rotation occurs between the chuck gear 614. Accordingly, the clutch 615 is the bulb material tube 40 when the bulb material tube 40 is to be rotated in order to evenly heat or blow the clamped bulb material tube 40 in a uniform shape. It transmits rotation so as to rotate together with the clamping means 620, supplying a new bulb material pipe 40 to the clamping means 620, or detaching the processed bulb 62 from the clamping means 620 In order to open the gripping portion in order to block the rotation by the slip generated in the clutch 615. On the other hand, the torque applied between the guide portion 621 and the chuck gear 614 so that the clutch 615 is slipped to an external force of a predetermined magnitude or more applied by the clamping release devices 720 and 730 to the lower surface of the pressing plate 624. Is caused by. That is, an external force of a predetermined magnitude or more that the clamping release devices 720 and 730 exerts on the lower surface of the pressing plate 624 to push the pressing plate 624 upwards may not only move the pressing plate 624 upward, but also the clamping. The friction force generated at the contact portion of the release devices 720 and 730 and the pressing plate 624 becomes a torque that the clutch 615 can slide to stop the rotation of the clamping means 620.
